How to Estimate Bathroom Remodel Cost (2026) — Contractor Pricing Guide

Bathroom remodels are one of the most common residential projects — and one of the most difficult to estimate accurately. The scope can swing wildly from a simple cosmetic refresh to a full gut job with plumbing relocation and custom tile work. Getting the number right matters. Underbid and you lose margin. Overbid and the homeowner calls someone else.

This guide breaks down bathroom remodel costs by component, explains how square footage drives pricing, and walks through how to build a professional line-item estimate that holds up when the walls come open.

National Average Bathroom Remodel Costs (2026)

Before diving into components, here are the national benchmarks contractors are seeing in 2026:

| Scope | Cost Range |

|---|---|

| Basic remodel (cosmetic, same layout) | $8,000 – $15,000 |

| Mid-range remodel (new fixtures, tile, vanity) | $15,000 – $30,000 |

| High-end / master bath | $30,000 – $80,000+ |

These ranges assume a typical 50–80 SF bathroom with no structural changes. A small powder room can come in under $5,000 for a basic refresh. A master bath gut renovation with a custom steam shower and radiant heat floors can push $100,000+.

The single biggest cost driver is whether the plumbing moves. If the toilet, shower, and sink stay in the same footprint, you're looking at a moderate project. The moment a homeowner wants to flip the vanity to the other wall or convert a tub to a walk-in shower, you're cutting into the floor, rerouting drain lines, and adding $1,500–$4,000+ before you've touched a single tile.

Bathroom Remodel Cost Breakdown by Component

Demolition and Hauling

Scope: strip existing tile, remove vanity, toilet, tub/shower unit, haul everything out. Cost range: $500 – $1,500

For a basic bath demo this is straightforward. Costs rise when you have double-layer tile over cement board (adds cutting time), fiberglass tub surrounds that need to be broken out in pieces, or limited dumpster access in a condo. Budget $500–$800 for a simple demo and up to $1,500 if the job is messy or multi-story.

---

Drywall and Cement Board

Scope: demo often exposes compromised drywall or outdated greenboard behind the tile. Wet areas need cement board or equivalent waterproof backer. Cost range: $1,500 – $3,500 (prep, materials, installation)

Cement board runs $0.50–$1.25/SF for materials. Labor to hang, tape, and waterproof the shower niche and pan area typically runs $800–$1,800 depending on complexity. Factor in drywall for the dry areas plus any framing repairs found during demo.

---

Tile Work

Tile is usually the biggest line item after labor overhead. Pricing breaks into two zones: shower walls and floor. Shower tile (walls):

• Materials: $8 – $25/SF (standard ceramic/porcelain to large-format stone)
• Labor: $6 – $12/SF
• Total installed: $14 – $37/SF

  A 60 SF shower (three walls to shoulder height) with mid-range tile runs $1,500–$3,500 just for the shower walls. Floor tile:

  • Materials: $3 – $15/SF
  • Labor: $4 – $8/SF
  • Total installed: $7 – $23/SF

    A 50 SF bathroom floor at mid-range tile is $600–$1,500 installed. What drives tile labor costs up:

    • Diagonal patterns (+15–25% labor)
    • Mosaic tile, penny tile, or herringbone (+30–50% labor)
    • Large-format tile (24×48+) requires larger substrate prep and more difficult cuts
    • Niche and shelf work adds flat labor per unit ($75–$200 per niche)
    • Heated floor mat under tile adds $300–$800 for a 50 SF floor

      ---

      Vanity and Faucet Materials: $400 – $4,000+

      • Stock vanity (24–36"): $400 – $900
      • Semi-custom (36–60"): $900 – $2,500
      • Custom or furniture-style double vanity: $2,500 – $6,000+
      • Faucet: $80 – $600 (builder grade to premium) Install labor: $200 – $400

        This is one of the easier installs when drain and supply lines don't move. Costs increase with double vanities, vessel sinks (which require different drain rough-in height), and wall-mounted faucets that require in-wall plumbing work.

        ---

        Toilet Materials: $100 – $800

        • Builder grade (1.28 GPF elongated): $100 – $250
        • Mid-range comfort height: $250 – $500
        • Wall-hung or smart toilet: $500 – $2,000+ Install labor: $150 – $250

          Straightforward replacement. Costs spike if the flange is rusted, cracked, or at the wrong height — flange repair adds $150–$400.

          ---

          Shower and Tub

          This is the most variable line item on any bathroom estimate. Prefab / stock units:

          • Fiberglass tub/shower combo: $300 – $800 materials
          • Alcove tub (soaking): $400 – $1,500
          • Prefab shower pan (32"–60"): $200 – $800
          • Install labor: $400 – $900 Custom tile shower:
            • Custom pan (mud bed or linear drain): $800 – $2,000 labor + materials
            • Tile walls (see tile section above)
            • Glass enclosure or frameless door: $800 – $2,500
            • Total for a custom tile shower: $3,000 – $8,000 depending on size and materials Freestanding tub:
              • Materials: $600 – $4,000
              • Requires floor-mounted or deck-mounted filler — budget an extra $300–$800 for the faucet and install

                ---

                Plumbing Rough-In (If Moving Fixtures)

                If the layout stays the same, plumbing labor is minimal — reconnecting supply and drain lines to new fixtures runs $400–$800 total.

                If fixtures are moving: Cost range: $1,500 – $4,000

                Moving a toilet or shower drain means cutting the subfloor, rerouting the drain stack, and roughing in new supply lines. In a slab house, this involves concrete cutting — add $500–$1,500 for the saw cut and patch. Factor this as a major budget line whenever a homeowner asks to change the bathroom layout.

                ---

                Electrical

                Scope: GFCI outlets (code requires them within 36" of any sink), exhaust fan, vanity lighting circuit. Cost range: $500 – $1,500

                A basic bathroom electrical update (one GFCI, new exhaust fan, update light fixture) runs $500–$800 with a licensed electrician. If the panel needs a new circuit for a heated floor or spa tub, budget $900–$1,500+.

                Exhaust fan replacement is $150–$350 depending on whether the duct path needs to be rerouted through the ceiling to the exterior.

                ---

                Paint

                Scope: ceiling and walls after tile and fixtures are in. Typically one accent wall and three other walls. Cost range: $300 – $600

                Bathroom painting is fast work but requires moisture-resistant primer and semi-gloss or satin sheen. Budget $300–$400 for a standard 50–70 SF bath and up to $600 for a larger master bath with ceiling detail.

                ---

                How Square Footage Affects Your Estimate

                Square footage is a useful reference point, but it's not a reliable pricing tool on its own. Here's why: Tiny bathroom (35 SF or less):

                A powder room or hall bath under 35 SF actually costs more per SF because the fixed costs — permits, demo, minimum tile materials, toilet, vanity — don't scale down. A tight bath remodel can run $250–$350/SF fully loaded. Mid-size bath (50–80 SF):

                This is the typical full bath. Total project costs of $15,000–$25,000 for a mid-range remodel work out to $190–$350/SF. Large master bath (100 SF+):

                As square footage increases, cost per SF typically drops into the $150–$250 range for mid-range finishes — because you're spreading permit and mobilization costs over more material. The better unit of measure is fixture count. A bathroom with a tub, separate shower, double vanity, and toilet is three to four times the scope of a single-fixture powder room — regardless of square footage.

                How to Write a Bathroom Remodel Estimate

                A professional bathroom estimate has three parts: scope definition, line items, and exclusions.

                Scope Definition

                One paragraph at the top of the estimate that defines what you saw and what you're doing. Example: "Full gut remodel of master bathroom (approx. 85 SF). Includes demo of existing tile, tub, and single vanity; cement board installation in shower area; custom 48" tile shower with frameless door; 60" double vanity; new toilet; tile floor; and painting. Plumbing and electrical fixtures remain in current locations."

                This one paragraph prevents 90% of scope disputes.

                Line Items to Include

                A thorough bathroom remodel estimate includes:

                • Demo and haul-off (broken out as a separate line)
                • Permit and inspection fee (see below)
                • Drywall / cement board (materials + labor)
                • Waterproofing membrane (if custom shower)
                • Tile — floor (materials + labor, noted in SF)
                • Tile — shower walls (materials + labor, noted in SF)
                • Tile — any accent bands or niches (noted as each)
                • Shower pan or mud bed
                • Glass shower door / enclosure
                • Vanity and countertop (materials separate from install)
                • Faucet(s)
                • Toilet
                • Mirror / medicine cabinet
                • Exhaust fan
                • GFCI outlets
                • Vanity light fixture
                • Paint (materials + labor)
                • Cleanup and final punch

                  Breaking materials and labor into separate line items looks more professional and gives homeowners a clear picture of where the money goes.

                  What to Exclude (And Say So)

                  List everything that's not in scope:

                  • "Subfloor repair or replacement — if the subfloor is damaged after demo, it will be scoped and priced separately."
                  • "Mold remediation — if mold is discovered behind tile during demo, work will pause for evaluation and a change order."
                  • "Electrical panel upgrade — existing circuit assumed adequate."

                    Homeowners appreciate the transparency. It also protects you from "I thought that was included" conversations.

                    Common Hidden Costs in Bathroom Remodels

                    Bathroom walls lie. Here are the surprises that show up after demo that should be in your contingency planning: Mold behind tile: $500 – $2,000

                    The most common hidden cost in bathrooms, especially in older homes with fiberglass tub surrounds. Greenboard (regular moisture-resistant drywall) behind tub surrounds eventually fails. When it does, mold follows. Remediation runs $500–$2,000 depending on extent. Some jobs require a licensed mold contractor. Outdated plumbing: $800 – $3,000

                    Galvanized supply lines from the 1960s–80s are corroded on the inside. The first time a plumber puts a wrench on the shut-off valve, it crumbles. Replumbing the bathroom supply lines to the main adds $800–$1,500. If copper-to-plastic transitions fail or the drain P-trap is cast iron, budget more. Permits: $150 – $400

                    Most full bathroom remodels require a building permit, and some jurisdictions require separate plumbing and electrical permits. The permit fee itself is $150–$400 in most markets. More importantly, a permit requires inspections — factor in scheduling delays if your jurisdiction is slow. Subfloor damage: $400 – $1,200

                    Toilet flange leaks and tub surround failures rot the subfloor over years. You won't know until the tile is off. Keep a contingency line in every bathroom estimate for subfloor sistering or patch — usually $400–$1,200 for a typical section.

                    Why Bathroom Remodels Need an In-Person Estimate

                    Bathroom remodels are one project where a phone-call price or a flat per-SF estimate will get you into trouble. Here's what you can only learn on site:

                    • What's behind the wall — is it cement board or rotted greenboard? Single-layer tile or double-layer?
                    • The drain configuration — is the tub drain on the left or right? Is there a floor drain? Does the shower pan drain tie into the toilet stack or a separate line?
                    • Ceiling height — a 10-foot ceiling in a master bath changes tile quantities and ladder work significantly
                    • Access — is this a second-floor bathroom with tight stair access for a dumpster haul? Is there an adjacent bedroom where dust protection needs to go?
                    • Existing fixture condition — the toilet and vanity might be "reusable" until you pull them and find the flange is shot

                      The fastest estimates are not necessarily the most competitive. Homeowners getting three bids will often choose the contractor who walked the job and asked the right questions — because they sound like they know what they're getting into.

                      ---

                      Estimating Bathroom Remodels Faster with AI

                      The challenge with bathroom remodels is that scope varies so much that building a template estimate is only marginally useful. What experienced estimators do is keep a mental library of unit costs — and apply them quickly in the field.

                      AI estimating tools like Ontrakt are changing that workflow. You upload photos of the existing bathroom — floors, walls, shower, vanity area — and the AI identifies the existing finishes, flags visible damage, and generates a structured line-item estimate in about 60 seconds. It's not a final bid, but it's a solid starting point that you review, adjust, and send as a professional PDF.

                      For remodeling contractors doing multiple estimates per week, that shift from "2-hour spreadsheet" to "15-minute review" adds up fast — especially when you're competing for jobs where the homeowner wants a number by end of day.
